Many people who never considered growing weed are most likely rethinking this; the new legislation in Ontario is now allowing residents within the province to grow four cannabis plants for personal use. In addition to this, the ACMPR has also been granting Canadians throughout the country licenses to grow for medical use for several years now. Whether you wish to grow four recreational plants or you would rather grow for medical purposes and receive your ACMPR license to legally grow medicinal marijuana, there are some helpful tips for new and more seasoned growers to ensuring the healthiest cannabis plants possible.
It is obvious that plants need light in order to perform the much-needed process of photosynthesis. But keep in mind that not only light is important, complete darkness is also a necessary step for proper flowering. During the flowering phase, there should be 12 hours of intense light followed by 12 hours of complete darkness. This means you need to secure your room by making it light proof, covering up any potential light leaks during those nighttime hours.
As far as which lights to choose, you can pick between LED or HPS bulbs. There should be a higher light intensity during the flowering phase, and also be sure to install reflective walls and ceiling so your plants can benefit from the light as much as possible.
Not only is it crucial to circulate the air throughout the room, it is important to bring in fresh air as well as expel the old stale air. Use vents to extract outgoing air and bring in fresh air, but be sure to allow all outgoing air to first pass through a carbon filter to diminish the skunky scent of your plants. Set up fans throughout the room to keep the air circulating, and if you have the means consider investing in a CO2 generator to supply your plants with even more carbon dioxide crucial for photosynthesis.
Deciding when your plants need water can be tricky, and it depends greatly on your pot size. You’ll start to get to know your plants quickly and learn when they are thirsty for water, so just keep an eye on them and look for tell-tale signs like droopy leaves and light/dry pots. It is really important to check the pH and temperature of the water you use. The pH should be between 5.5 and 7, with optimal levels around 6.2. Invest in an accurate pH meter, as well as products to help you adjust the levels. Lastly, make sure you don’t shock your plants with water that is too cold or too hot. The temperature should range from 60 to 68 degrees Fahrenheit, and colder or hotter can affect the health of your plants.
Same with the temperature of your water, the temperature of the actual room is very important. Keep your room around 75 degrees – don’t go above 86 or below 64. Depending on where you are living in Canada, you might need to think about a heating or cooling system.
Your plants live off of light, water, and proper nutrients. The main nutrients you will need to provide are phosphorous, nitrogen, and potassium. There are lots of nutrient blends on the market to choose from, so start testing some out or even creating your own blends. A common mistake made by growers is giving your plants too many nutrients – this can be just as harmful as not enough nutrients!
